  2. September 2010 Newsletter

  3. A Welcome from Transportation Secretary Carolann Wicks I am pleased to welcome you to the inaugural edition of Building for Tomorrow: The Indian River Inlet Bridge Newsletter. This newsletter is intended to give you an insider’s view into the world of building the Indian River Inlet Bridge. The information that you will find within these pages will give you the opportunity to not only familiarize yourself with the bridge building process, but also to learn about one of the largest projects to ever be undertaken by the Delaware Department of Transportation. DelDOT is committed to giving students, teachers, and parents the opportunity to learn about this bridge and everything that is going into building it. Remember that no matter who you are or where you come from, you should never stop learning. I hope that you find this newsletter to be a fun and interesting tool to use as you continue learning.

  4. A Moment of Bridge History This is a photo of the creosote timber bridge that spanned the inlet in 1934. It was built with timber that came from a plant in Newport. Due to an increased need for large ships to travel through the inlet, this bridge was replaced in 1940. In addition, the design of the 1934 bridge was problematic. It was made from wood, which we learned does not hold up in an environment with a lot of water. Also, its piers were in the water and were exposed to strong currents, which weakened the support piers. Four bridges have spanned the inlet since 1934. With each bridge, engineers learned how the land, environment and weather impacted each bridge.

  5. The Indian River Inlet Bridge • Background • Existing Indian River Inlet Bridge carries Route 1 traffic over the Indian River Inlet between Bethany Beach and Dewey Beach. • The bridge is also known as the Charles W. Cullen Bridge. • Current bridge was built in two parts: • In 1965, a portion of the bridge was constructed to carry two-way traffic, one lane in each direction. • In 1976, additional structure width was added which allowed for two lanes of traffic in each direction separated by a median barrier.

  6. CURRENT PROJECT • SKANKA Southeast was awarded the $150 million design-build contract in August 2008. • The new bridge will be 2,600 feet long • 900 feet over the inlet • 1,700 over land • Each side is supported by two 249 foot tall pylon towers. • All supports are out of the water eliminating the impact from strong water currents which occur now with the existing bridge. • The bridge will include: • Two 12-foot wide travel lanes. • A 12-foot wide multi-use sidewalk for cyclists and pedestrians.

  9. Design Elements Chosen by You! In the Spring of 2009, DelDOT worked with community members who played an important part in the design process as they ultimately decided how the bridge would look. Over 1,100 votes were cast and the public’s choices are being incorporated into the new bridge right now during construction. Here are the choices and the final decisions!

  10. Design Element 1 – Cable Stay Color Option 1 – White Cable Stays Option 2 – Gray Cable Stays Option 3 – Blue Cable Stays

  11. Design Element 1 - Winner Option 3 – Blue The cable stays are one of the most noticeable features of the new bridge and, because of that, their color was very important. Blue was the overall winner with 827 votes. Although the color makes the cable stays look nice against the backdrop of the ocean, it also serves a more important purpose. The light color shade helps to reflect the heat of the sun, which during the summer can be a lot. If the cable stays were a darker color like black or navy blue, they would absorb the heat, which would not be good for the cable stays and the cables inside of them.

  12. Design Element 2 – Pylon Top Option 1 – Slanted Top With Railing Option 2 – Slanted Top Without Railing Option 3 – Slanted Top With Slot

  13. Design Element 2 - Winner Option 1 – Slanted Top With Railing The slanted top with railing was the overall winner with 504 votes. This area of the pylon, its highest point, is home to the beacon that will assist pilots flying planes. By law, each pylon must have a beacon. The person going up to maintain the beacon will be over 250 feet in the air!

  14. Design Element 3 – Lighting Features Option 1 – Recessed Semi-Circle Round Option 2 – Recessed Rectangle Option 3 – Recessed Nautical

  15. Design Element 3 - Winner Option 3 – Recessed Nautical The public had the opportunity to choose the lighting fixture that will line the public walkway over the bridge. The recessed nautical option was the overall winner with 762 votes. The fixtures will be activated at night to enable people walking over the bridge to have a safe, lighted walkway to use when crossing from one side to the other.
